The planting is all part of a greening project in the south Baltimore neighborhood that the mayor hopes will set an example for other neighborhoods around the city.

"Federal Hill is a unique, a historic neighborhood, so to see this greening project, with the businesses community and the residents all working together in partnership with the city, that's how we're going to get Baltimore growing all over the place," Rawlings-Blake said.

Federal Hill Thinking Green is a cooperative effort between the residential and business communities in Federal Hill coming together with a common goal of cleaning up and bettering the neighborhood.

"I think the fact that we were able to get all the businesses, the three different associations and the neighborhood association together for something that contributes to the betterment of the entire neighborhood is something we can all share. It's a win-win for everybody," said Eric Costello, the Federal Hill Neighborhood Association president.

With funds coming from the neighborhood itself, there are three phases in place to last through 2015, which includes planting trees, uprooting dead ones and maintaining trees that are healthy, officials said.

Richard Polan, who has been proclaimed the Federal Hill tree guy, said trees are a great place to start making a neighborhood look and feel better.

"I'm very grateful that we have a turnout like this just to help share information and awareness about our green canopy in the city," Polan said.

There are hopes to expand the program in the coming years to other parts of south Baltimore and Locust Point.
